REGEPTACLE-CLOSURE.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed April 9, 1906. Serial No. 310,659.

To all whom 'it may concern:

Be it known that we, ANDREAS RAsMUssnN and MARTIN OLSEN, subjects of the King of Norway, both residing at Stavanger, Norway, have invented certain new and useful Improvements in Receptacle-Closures; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art 'to' which it appertains to make and use the same, reference being had to the accompanying drawings, and to' letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to packing receptacles and consists in improvements, which facilitate the manufacturing sealing and the opening of the same. Hitherto it has been usual to provide in the lid or closure of such receptacles, especially that kind of receptacles, which are used for sardines and anchovies, weakened lines, extending from the ends of a short slot in the closure, and to fasten by soldering at the inside of the closure between the said weakened lines a strip of sheet metal, extending through the slot and ending as a tongue outside the slot. hen the receptacle is to be opened this or key, which then is rotated, whereby the part of the closure lying between the weakened lines is wound up.

This invention consists in such an arrangement of the means for opening receptacles, that the use of soldering by making and sealing the receptacles is completely avoided. This is obtained by arranging the opening tongue in such way that a part of the same may be spun into the seam. The tongue may be made in one piece with the closure or may consist of a separable piece.

In the annexed drawing, Figures 1. and 2, show respectively in a plan and a vertical sectional view one form of our invention, in which the closure and the opening tongue are made in one piece. Figs. 3, 4; and 5 show on an enlarged scale sections through a seam Referring first to the form illustrated in Figs. 1 and 2, the tongue is arranged as a part a integral with and projecting from the short side of the closure 6 of the receptacle. The weakened line 0 begins at the points, where the tongue fits to the rim of the closure, said line being also extended over the rim (5 of the material of which the seam or joint is formed; it may of course also be placed in its entire length in this rim.

In the modified form shown in the Figs. 35 the tongue a is made of a separable piece of waste material and is placed loosely inside the closure (2. By the spinning operation the inner part of the tongue is spun into the seam together with the rim of the closure and is thus joined with the receptacle.

When opening the receptacle, the tongue in both constructions will at first cause a bearing throu 'h of the joint and then the winding up 0 the closure takes place, and when a separate tongue is used, as shown in Figs. 35, this tongue is not wholly released from the joint, until the outer detached part of the latter has been wound so far around the key, that the complete bearing up of the closure is secured.

The arrangement and the shape of the tongue may be varied according to the shape of the receptacle, the qualities of the joint and the like and also the weakened line may have any suitable form and may be made in any suitable way.

We claim- 1. In combination with a packing receptacle, of a closure therefor having its rim spun into the rim of the receptacle forming a connecting seam, and a tongue spun into said seam having a portion projecting out of the same, said closure having weakening lines extending into the seam at both sides and close to the tongue forming a continuation of the outlines of the latter.

2. In combination with a packing receptacle, of a closure therefor having its rim spun into the rim of the receptacle forming a connecting seam, a separate tongue spun into said seam having a portion projecting out of the same, said closure having weakening lines extending over the edge of the receptacle into the seam at both sides and close to the tongue.

3. A receptacle comprising a sheet-metal box having a flanged edge, a cover having its edge spun around the flange and provided with weakening lines extending to the edge I as our invention, we have signed our names of the cover and embracing the contour of 1 1n presence of two subserlblng Witnesses.
